Japanese species of the genus Intybia are revised taxonomically, with the examination of the endophallic structure. Eight species, including one new species Intybia donan sp. nov. from Yonaguni-jima, are recognized. All species are described or redescribed with a key and figures. The endophallic structure contains one primary sclerite (gonoporal piece), three secondary sclerites (ligula, semi-gonoporal piece, and spinous plate) in some species, and a membranous basal area densely covered with many spines (spinous area). Based on the structures of the endophallus, the Japanese members of the genus are divided into two species groups (the histrio and pelegrini groups). The pelegrini species group is furthermore subdivided into three subgroups (subgroups 1–3). New distributional records are as follows: I. histrio from Hachijô-jima and Tanega-shima; I. niponica from Sakhalin and I. takaraensis from Tokuno-shima and Amami-Ôshima.

The Helina obtusipennis species-group is erected for nine species of Helina in the Palaearctic and Oriental regions, namely H. atlantica (Tiensuu), H. ciliatocosta (Zetterstedt), H. eurymetopa Emden, H. macrocera Hennig, H. mandschurica Hennig, H. medogensis sp. nov., H. obtusipennis (Fallén), H. setigera (Pokorny), and H. spinicosta ( Zetterstedt). These species are Palaearctic in distribution except for H. eurymetopa Emden and H. medogensis, which are known from the Oriental Region. Members of this group can be easily differentiated from those of other Helina species-groups by their broad frons in both sexes with one or two pairs of upper orbital setae. A key to the males of the H. obtusipennis species-group is given.

The species group effusus of the genus Pyrops Spinola, 1839 is reviewed and the nomenclatural history of the genus Pyrops is briefly summarized. One new species from eastern Borneo, Pyrops synavei sp. nov., is described. P. gunjii (Satô & Nagai, 1994) stat. nov. is proposed as a valid species instead of a subspecies of P. whiteheadi (Distant, 1889). P. maquilinganus (Baker, 1925) is removed from the effusus group and placed back into the candelaria group. P. cyanirostris (Guérin-Méneville, 1845) is removed from the group and not attributed to any of the currently defined species groups. An illustrated key to the species of the group with the addition of P. intricatus (Walker, 1857) and a distribution map are given. The effusus group is restricted to Borneo and adjacent Laut Island and presently contains 4 species: P. effusus (Distant, 1891), P. gunjii (Satô & Nagai, 1994) stat.nov., P. synavei sp. nov. and P. whiteheadi (Distant, 1889). Trophobiosis observations with the gecko Gehyra mutilata (Wiegmann, 1835) (Reptilia: Squamata: Gekkonidae) and two species of cockroaches (Insecta: Blattodea), one Dorylaea sp. and an unidentified species of Pseudophyllodromiinae, are reported and illustrated for P. whiteheadi; observation with a cockroach, Dorylaea sp., is reported for P. intricatus.

The geminia and semiobsoleta groups of the genus Cyphura Warren, 1902 (Lepidoptera: Uraniidae) are revised. Five new species are described. There are four new species in the geminia species group: Cyphura pallidata sp. n., C. marcoi sp. n., C. aruensis sp. n., and C. numforensis sp. n. In this group, a lectotype is designated for Strophidia costalis Butler, 1887, C. subsimilis Warren, 1902, S. bifasciata Butler, 1879, C. catenulata Warren, 1902, Urapteroides approximans Swinhoe, 1902, U. falka Swinhoe, 1916, U. swinhoei Rothschild, 1915 and for U. swinhoei Joicey & Kaye, 1917. Six new synonyms are proposed: U. gutturalis (Swinhoe, 1916) is a junior synonym of C. geminia (Cramer, 1779), C. subsimilis Warren, 1902 is a junior synonym of C. costalis (Butler, 1887), C. catenulata Warren, 1902 and U. approximans (Swinhoe, 1902) are both junior synonyms of C. bifasciata (Butler, 1879), U. falka (Swinhoe, 1916) is a junior synonym of C. pieridaria Warren, 1902 and U. swinhoei (Joicey & Kaye, 1917) is a junior synonym of C. maxima (Strand, 1912). Urapteroides swinhoei Rothschild, 1915 is transferred to Cyphura as Cyphura swinhoei (Rothschild, 1915) comb. n. In the semiobsoleta species group, one new species is described: C. trifasciata sp. n. In this group a lectotype is designated for Urapteroides semiobsoleta Warren, 1896, U. semiobsoleta reducta Joicey & Talbot 1916, C. multistrigaria Warren, 1907 and for C. multistrigaria ab. dealbata Warren, 1907.

The endophallic structure of the genus Laius is studied and discussed based on the examination of 19 species from Asia to the Indian Ocean. The structure contains two primary sclerites (named gonoporal piece and ligula), a secondary sclerite on the basal part of the gonoporal piece (named additional sclerite) in some species, and a membranous basal area closely covered with many spines (named spinous area). Five species groups are recognized based on the morphology of the endophallic sclerites. The sympatric species have different body sizes and quite distinguishable endophallic sclerites (= different species group), while the allopatric species have overlapping body sizes and similar endophallic sclerites (= same species group). Three new species are described and six previously known species are redescribed with endophallic sclerites, and the descriptions of endophallic sclerites of the remaining ten species are added. The larva of Laius rodriguesensis sp. nov. is also described. The genus Nossibeus Evers, 1994 is synonymised with Laius Guérin-Méneville, 1830.

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

The giant water bug fauna from tropical South America remains poorly known. Three species of Belostoma Latreille (Belostoma fittkaui De Carlo, B. sayagoi De Carlo and B. hirsutum Roback & Nieser) have been cited only a few times in the literature. These three species are remarkable since they represent an extreme variation for the genus, with article II of the labium distinctly shorter than article III. Here, the synonymy of B. hirsutum with B. sayagoi is proposed based on examination of type material and additional specimens. Further, B. fittkaui and B. sayagoi are redescribed, including discussion about comparative morphology with congeners. A new species group is proposed for these species and a key to the Belostoma species groups is provided. Distribution records are also updated.

The morphology of the genus Scapheremaeus Berlese, 1910 is reviewed and characters of taxonomic utility delineated. Based on the morphological review, some 13 species-groups are outlined based on major morphotypes. There are two main categories: i) species that have a complete circumdorsal scissure with plicate microsculpture on the circumnotogastral plate and strongly contrasting microsculpture (foveolae, ridges or tubercles) on the centrodorsal plate (plicate species-groups), and ii) species with the circumdorsal scissure complete, incomplete or absent but with little or no contrast in microsculpture between the central and lateral regions: typically both regions foveolate or reticulate (non- plicate species-groups). A catalogue of world species of Scapheremaeus is provided. Scapheremaeus petrophagus (Banks, 1906) is not a Scapheremaeus but belongs to an undetermined genus in the Ameronothroidea. Cymbaeremaeus cyclops Oudemans, 1915 is recombined to Scapheremaeus. Five new species are described (S. angusi sp. nov., S. cheloniella sp. nov., S. ewani sp. nov., S. lambieae sp. nov., and S. pulleni sp. nov.) from soil and litter habitats in semi-arid Mallee eucalypt vegetation at Bookmark Biosphere Reserve, South Australia. These are the first members of the genus Scapheremaeus to be described from Australia, though undescribed species have been recorded previously. All the new species are morphologically closely-related and belong to a single species-group: Carinatus.
